HOPLODACTYLUS POMARII. 295 



cave upon the middle, and, when seen from above, has the shape of 

 an acute triangle rounded at the summit. Its upper surface is minutely 

 granular upon the posterior region ; the granules being somewhat 

 larger on the frontal and rostral regions. The internasal space is 

 covered with ten or twelve small hexagonal plates : the middle ones 

 being a little larger than the peripheric. The nostrils are conspicu- 

 ous, lateral, situated immediately behind the rostral plate and above 

 the first labial. The rostral plate itself is rather large, parallelo- 

 gramic, nearly twice as long as deep, subconcave upon its upper edge. 

 The upper labials are thirteen on either side, anteriorly deeper than 

 long, and diminishing gradually backwards to the last one, which is a 

 minute plate. The symphyseal is smaller than the rostral, subtrian- 

 gular in shape, and entirely inclosed by the first pair of lower labials, 

 of which there are eleven or twelve pairs equally diminishing back- 

 wards, so as to make of the last a very small plate ; they extend a 

 little further back than the upper labials; the anterior two are much 

 deeper than long : the third being nearly subquadrangular ; the rest 

 diminish suddenly from the fourth, besides tapering off posteriorly. 

 There are no mental shields, properly so called : the chin is protected 

 by very small, subhexagonal plates. The rest of the under surface of 

 the head, the throat, and neck is minutely granulated. The sides of the 

 neck exhibit a few oblique folds, being covered, as well as its upper 

 surface, with minute granules, like those of the posterior region of 

 the head. The auricular aperture is rather large, and obliquely sub- 

 elliptical. The eyes are large and circular, the eyelid being provided 

 with small, subconical, erect, granular scales : the pupil is vertical. 



The body is elongated, subcylindrical, depressed, covered above 

 with small granules, slightly larger than on the posterior portion of 

 the head and neck. The pectoral and abdominal regions exhibit very 

 small, equal, subrhomboid, or subcircular scales, somewhat larger upon 

 the interfemoral region, where they are perforated : the pores being 

 disposed upon five ogees, closely set together, and fitting into one an- 

 other: the exterior one, the largest, being composed of fourteen pores. 



The limbs are well developed, though slender ; the anterior pair 

 extending over two-thirds of the distance towards the groins, when 

 stretched backwards alongside the body ; and the posterior pair 

 three-fourths, towards the axillae, when dealt with in an analogous 

 manner. The supero-posterior surface of the arms, forearms, legs, 

 thighs, and tarsi, is granular, whilst their antero-inferior surface, as
